England's star trio struggle to fit in the same lineup - does the manager have a point?
With six wins out of six, zero goals allowed and tournament placement confirmed with matches remaining, Three Lions boss Thomas Tuchel might claim he has got all of his big qualifying decisions correct.
Nevertheless, in the lead-up to Thursday's domestic match against Serbia, he initiated discussion when he said that three of the nation's top talents - Jude Bellingham, Phil Foden and Harry Kane - struggle to perform in the equivalent formation.
"At the moment, if we keep the structure, they cannot play.
"They might but not within this system, not for the balance that we established and not within the framework that comes also with wingers who are like specialists in their positions. We presently employ with specific numbered positions."
From certain starters to fighting for spots
The Manchester City and Real Madrid stars have been utilized out wide for England in the past, but his team selections indicate that the Barcelona loanee and Bukayo Saka are his first choices on the wide areas respectively.
So can Bellingham, Foden and Kane operate simultaneously?
Former Three Lions boss certainly thought so.
Bellingham, Foden and Kane started all of England's seven games at the European Championship in Germany, where the national squad were defeated by Spain in the final.
In the 16 fixtures the three have featured alongside each other, England have triumphed 10 times, shared points three times and lost three, scoring 36 times and allowing 14 goals.
Analysis: Foden's versatility gives Tuchel options
Tuchel has employed a four-two-three-one setup that transforms formation when England attack.
The young midfielder has been the key creative force because of his excellent dribbling, strike quality and ability to attack the box when the number nine withdraws.
Tuchel has mentioned preferring dedicated wide players. The wide attackers consistently operate in wide areas and can retain the ball skillfully, challenge defenders, and enter the area to finish.
Behind this front four, Tuchel plays with a midfield two consisting of one defensively strict player and a partner with attacking liberty to support offensive play.
What solutions exist for the trio?
Foden and Bellingham would be vying against other creative midfielders for the number 10 role, with Kane likely to start up front.
Foden could feature as the main forward, which theoretically could permit both Bellingham and Foden to feature instead of Kane.
There is one way all three could play in this system and Tuchel suggested it this week.
"For Man City, he operates similarly to a box-to-box or creative role, so potentially in future we regard him as a central midfielder," he said.
Foden has been deployed in a versatile central position this season.
That has allowed him to take responsibility deeper and could categorize him as the advanced playmaker, alongside a holding midfielder.
This would then enable Bellingham to operate as the creative force and Kane as the center forward.
Regardless of if Tuchel opts to structure the side like this at the World Cup, what seems encouraging is his readiness to exclude star names in the interest of team harmony.
